[Ifeffit] Debye Waller for first shell and second shell

Dear All, Does the Debye Waller value for the first shell have to be smaller than that of the second shell? can you have a situation where the Debye Waller value for the Zn-O first shell is 0.011 and for the Zn-Fe second shell is 0.003? so if there is thermal or static disorder in the first coordination shell,that must be the case for the second coordination shell?
